I'm going CRAZY!!

[Tammie Godden]

Good Morning

Please help! I have imported my CAD, and have been trying to select a circle to measure For, instance, I am trying to get the center for the circle, I select the locations, with my mouse, that I want to use to define the circle. Its good for the first 2 hits, then as soon as I select the third location, the feature turns into a HUGE circle and on the grapics display, it goes around the whole part! What am I doing wrong?

[Bill **********]

Are you using wire frame? It sounds to me like the third pick is grabbing something you don't want in the feature.

Are you using wireframe or surface? Try takeing the 3rd hit in between the first 2 and then change the start angle and stop angle to 0,0 Some times the cad is not a full circle and it can not find it and will grab another cad element.

Welcome to the asylum!

What you may have to do is to create a new layer of data and put into it JUST the piece of data that has the hole in it. I have run into this several times, and as far as I can remember, EVERY time it was when I had to use a file from UG. The short-cuts used when the data was created do not translate well out from the native software. Making the new layer is easy enough using the VIEW SETUP, just try to make sure you only move what you need, then use JUST that layer when trying to pick the data for the circle.

Hmmm, what about the correct work plane?

Workplane is not an issue when dealing with DCC Features (auto features) and you are picking on the cad data to get the XZYIJK nominals.

Tammie are you there? Did they send you to the asylum, or did you run to the bar for some conseling? What happened?

[Tammie Godden]

Hi

Yeah, I'm here, grrrr!!

This CAD file was originally a UG file, which was translated into IGES. It is not just the circle I am having trouble with, it is everything! Even a simple vector point is all f#@*ed up. The bar? Sounds good to me! Unfortunately, I have to work through lunch and try and get this figured out.

Do I detect some hostility in Tammie's comment????????? Chances are it is just the cad file. Contact Engineering and send the problem back to them.

When I have had unlimted problems with a UG IGES file, I tell them to output it as a STEP file. I then use the step file instead of the IGES and most of the problems go away. There are still some messed up trimmed surfaces, but it is a lot better. I do NOT think that you have to pay extra for the ability to import STEP.

[Schrocknroll]

Are you using 3.7? I've had problems correctly importing IGES files created from UG when using 3.7. I had to import them into a new file in 3.5 then open in 3.7 and it worked fine.

Pretty sure that is a default 'flavor' of Pcdmis (step).
Good advice about the layer selection, that is what I do when I have a lot of prob's - Also seems step is a bit cleaner at times...

Alright, I have taken the above mentioned advise. Hopefully, I will receive new CAD this afternoon. I will let you know if it solves the problem.

[ag162]

I definately suggest getting a step file if possible. That format is more reliable than iges. Iges has translation problems with all versions.

Well, I give up. I had the CAD translated to STEP, and still no luck. I am beginning to think I am a complete moron. I need a vacation! I finally got the engineer to just pull the blasted points, and maybe by the end of the week I will have measured what I started last Friday. As always, you guys rock, thanks for your input.
